Problems solved by technology

Although the capture efficiency of the secondary flue gas of the converter has been improved to a certain extent, the capacity of the corresponding dust removal equipment must be expanded to increase the air volume of the system, which not only increases the initial investment of the equipment, but also greatly increases the operating cost, which cannot meet the national energy conservation and emission reduction requirements. related requirements

Abstract

The invention relates to a novel double-air port movable secondary flue gas gathering apparatus for a converter. The apparatus comprises a gathering cover arranged on the converter. The gathering cover is communicated with an exterior dedusting pipeline through an exhausting pipe and comprises a front panel, a top panel and a back panel, wherein the front panel, the top panel and the back panel are successively connected to form a hollow tank body with a lower opening, two ends of the hollow tank are both connected with the exhausting pipe, the top panel is provided with a shielding top board on which a distance detector is arranged, the shielding top board is connected with a fixing device through a driving mechanism, the distance detector controls telescoping length of the driving mechanism through a controller, and the front panel is provided with an air inlet. According to the invention, the shielding top board can fully shield a gap between a crane crossbeam and the gathering cover, which is beneficial for high-efficiency and low-consumption gathering of secondary flue gas of the converter before large-scale diffusion of the secondary flue gas, and energy conservation and environmental protection are realized.

Description

technical field [0001] The invention relates to a secondary flue gas purification facility of a steelmaking converter in an iron and steel enterprise, in particular to a novel double tuyere movable type converter secondary flue gas collecting device. Background technique [0002] As we all know, environmental protection is a basic national policy that must be adhered to for a long time. Under the strong promotion of national policies and the supervision of public opinion, all iron and steel enterprises have put forward higher requirements for the environmental protection of plant areas. [0003] At present, the traditional double tuyere movable converter secondary flue gas capture device cannot capture the flue gas generated during the production process of the converter with high efficiency and low consumption, which has caused pollution to the steelmaking workshop and the atmospheric environment to a certain extent, and also consumed Lots of energy. [0004] In order to i...
